Not to mention a van has the benefit of keeping the load dry
Which depending on what you do and where can be very important
They also keep dirt and road dust off your tools and materials. Vans also conceal your cargo better than a bed which can prevent theft. Most vans are more fuel efficient than similar sized trucks. Vans are usually easier to drive and have better visibility. A big enough van can fit a small workshop in the back, that you can stand in and assemble parts.
Vans are the better work/trade vehicles compared to trucks for most applications and that is a hill I will die on.
I use a 4 door short bed truck, and here’s why. I need to pick up my kids half the days of the week. I don’t have a van anymore because I do demo work and I got tired of riding inside with the dust. I just build a wood rack if i need to haul more. I’d get a 4 door, long bed truck, which would be the best ever except it’s just too dang long to park. So when the kids aren’t around I fold up the rear seats and the tool boxes go in there. Is what it is. I long for the days when I drove a car with a toolbag in the trunk.
